Detailed Embodiments

[0027] As Figures 1-6As shown in the figure, the utility model provides an automatic feeding mechanism, which includes a material storage rack 1, a support frame 2, a cross beam 3, a vacuum suction cup 10 and a controller 17. The upper surface of the support frame 2 is provided with a limit plate 13, a cylinder push rod 11 and a roller 15. One side of the support frame 2 is provided with a cross beam 3. Both ends of the cross beam 3 are provided with motor boxes 5. The inside of the motor box 5 is provided with a motor 18 and a gear 19. The gear 19 is arranged at the output end of the motor 18. Both sides of the support frame 2 are provided with racks 4 meshing with the gear 19. An electric push rod is installed on one side of the cross beam 3. The bottom of the electric push rod is provided with a connecting rod 8. The bottom of the connecting rod 8 is provided with a vacuum suction cup 10.

[0028] Furthermore, in this embodiment, a number of materials 14 are stored on the upper surface of the material storage rack 1. The material storage rack 1 is located at the input end of the support frame 2. The materials 14 are concentrated on the material storage rack 1, which is convenient for the suction cup on the cross beam 3 to adsorb the materials 14.

[0029] In this embodiment, an installation frame is arranged between the cross beam 3 and the electric push rod. The installation frame is fixedly connected to the cross beam 3 and is screwed to the electric push rod. The lower end of the electric push rod is provided with a connecting head 9. The upper surface of the connecting rod 8 is provided with a connecting plate 16 adapted to the connecting head 9. The electric push rod is installed on the cross beam 3 through the installation frame.

[0030] In this embodiment, a pin shaft connection is arranged between the connecting head 9 and the connecting rod 8. The bottom surface of the connecting plate 16 is provided with a number of vacuum suction cups 10. The vacuum suction cups 10 are in threaded cooperation with the connecting rod 8. The connecting rod 8 is connected to the push rod through the connecting head 9 and the connecting plate 16. The vacuum suction cups 10 are installed through the connecting rod 8. The vacuum suction cups 10 are externally connected to a vacuum pumping device.

[0031] In this embodiment, a drag chain 6 is slidably connected to one side of the support frame 2. The upper end of the drag chain 6 is screwed to one end of the cross beam 3. A sliding groove adapted to the drag chain 6 is opened on one side of the support frame 2. The movement of the cross beam 3 is stabilized through the drag chain 6.

[0032] In this embodiment, racks 4 are screwed to both sides of the support frame 2. The output end of the motor 18 is in transmission connection with the gear 19. The motor 18 is screwed inside the motor box 5. The motor box 5 is screwed to the cross beam 3. The gear 19 is controlled by the motor 18 to rotate along the rack 4, and the cross beam 3 connected to the motor box 5 is driven to move horizontally.

[0033] In this embodiment, a plurality of limiting plates 13 are equidistantly arranged on the upper surface of the support frame 2. The limiting plates 13 are designed in an L shape. The cylinder push rod 11 is arranged on one side of the support frame 2. A push rod is arranged at the front end of the cylinder push rod 11. A plurality of rollers 15 are embedded in the upper surface of the support frame 2. The moving material 14 is limited by the limiting plates 13 to prevent the material 14 from shifting. The shifted material 14 is pushed back into place by the cylinder push rod 11. The material 14 can move on the surface of the rollers 15 through the rollers 15, improving the smoothness of the movement.

[0034] In this embodiment, a proximity switch 20 is arranged at the outer end of the support frame 2. A displacement sensor 21 is arranged on one side of the connecting rod 8. The output ends of the proximity switch 20 and the displacement sensor 21 are communicatively connected to the output end of the controller 17. The moving position of the connecting rod 8 is monitored by the displacement sensor 21, that is, the extension length of the electric push rod is monitored. The proximity of the material 14 to the outermost end of the support frame 2 is monitored by the proximity switch 20.

[0035] Specifically, the material 14 is placed on the storage rack 1. The vacuum suction cup 10 is located above one side of the material 14. The staff controls the electric push rod to move downward through the controller 17. At the same time, the vacuum suction cup 10 is evacuated synchronously through a vacuum pumping device to adsorb the material 14. And the moving distance of the electric push rod is preset in the controller 17. The displacement sensor 21 on the connecting rod 8 between the electric push rod and the suction cup is used for monitoring. When the moving distance reaches the preset distance, the push rod stops moving downward;

[0036] After the adsorption is completed and the push rod stops moving for a fixed time, the time is timed by the timer built in the controller 17. The stop time is set according to requirements to ensure that the material 14 is adsorbed. After reaching the set time, the controller 17 controls the motor 18 in the motor box 5 to start. The motor 18 drives the gear 19 at the bottom to rotate. The gears 19 on both sides of the cross beam 3 move along the rack 4 on the support frame 2 in the output direction of the support frame 2. Since only one end of the material 14 is adsorbed and the other parts are inclined, therefore, the other parts in contact with the support frame 2 move based on the rollers 15 on the surface of the support frame 2, reducing the resistance of the cross beam 3 to drive the material 14 to move;

[0037] Through the proximity switch 20 at the outermost edge position in the output direction of the support frame 2, when the material 14 enters the detection range of the proximity switch 20, the proximity switch 20 will output a signal (such as an electrical signal). The controller 17 receives the signal and controls the vacuum suction cup 10 to stop evacuating, and the material 14 falls from the vacuum suction cup 10;

[0038] Then, observe the position of the material 14. If it is offset, control the push plate 12 through the cylinder push rod 11 on one side of the support frame 2 to push the material 14. The material 14 abuts against the outside of the limit plate 13 for position calibration. During the movement of the material 14, the material 14 is limited by the limit plates 13 on both sides. Therefore, when the material 14 moves, there will basically be no excessive position offset, and the feeding work is completed. The cross beam 3 resets, and the above actions are continuously performed for automatic feeding.

[0039] It should be noted that the control method of this application document is automatically controlled by the controller 17. The control circuit of the controller 17 can be realized by simple programming of those skilled in the art, which belongs to the common knowledge in the art. This application will not explain the control method and circuit connection in detail, and this application is powered by an external power supply.
